LinCom proposes to use the technology it developed to implement a frequency hopping cordless telephone and the technology it is developing currently to implement loss tolerant voice compression and combine it with encryption technology from VLSI Technology to implement a mobile radio network which can provide the following features: 1) A system robust against jamming. 2) A system with low probability of intercept. 3) A system offering voice and data encryption. 4) A frequency agile system intended for operation at any of the ISM bands defined by the FCC. 5) A system capable of providing interconnect between users or directly to a PSTN interface for plain old telephone service (POTS). 6) A system will allow for the development of low cost user terminals. (Less than $150) 7) A system which in the commercial marketplace could function as a wireless PBX/PABX system. 8) A system in which the headend equipment is mobile and can be redeployed quickly and effortlessly. (Less than 10 minutes). Anticipated Benefits: POWER System will provide reliable, secure voice and data communications with anti-jamming capability. The system will be mobile to provide communications in a dynamic, hostile environment. Systems costs and user terminals will be affordable and comparable to cellular phone costs. The system can be employed by the military for battlefield communications are in an office setting to be employed as an office PBX system.
